Fix oversight in check_ungrouped_columns optimization that avoids
unnecessary checks for complex grouping expressions: we cannot check
whether the expressions are simple Vars until after we apply
flatten_join_alias_vars, because in the case of FULL JOIN that routine
can introduce non-Var expressions. Per example from Joel Knight.
